Nanaka Kirisato

Nanaka is a senior high school student. For her, studying is the most important thing in the world so she has few friends. Due to circumstances, she gave up on her childhood early in life. One day, she received a shock and fell down a flight of stairs causing her to regress to a time when she was 6 years old. This 6-year-old Nanaka is a very spirited and is obsessed by a children's TV-show called Magiko Domiko. The 6-year-old Nanaka says "hayaya" and "hawawa" a lot. (Source: Wikipedia)
